Well... before I opened this thread, just based on the title, I was gonna say that my answer would be: "I don't have any cash, sorry."

But after hearing the full story, and hearing the circumstances...I probably would've given the guy the money. Or at least helped him find $4 in cash. Or helped him find a taxi.

(Regardless of whether or not he was lying, I would just feel too guilty saying "Sorry, can't help you!" to someone whose mother may have just died.)
